Engine wont start!!!!!

Lets see if the problem was solved! They also dont have a clue if the problem was from the part they changed!!!!

It seams that are more cars apearing with the same problem in Europe!
Factory didn't came up yet with a solution, but the problem is in that fuse box changed in my car, but there is a problem with the production of that fuse box, and no other to replace it yet!


It seems that many w204 are starting to have this problem in europe, at the beging mine was one of the few but now...
Factory know that there is a problem with the fuse box, and changed mine, but the current fuse boxs are the same!
They are changing production to fix the problem, till them, no fixed part!!!

On diesels it could be an issue with high pressure build up but isn't the CPS more likely in your case? Did you say how old the car is, I can see that it does not have a lot of miles but I had a CPS sensor recall on my W221 (even if it had no issues), just wandering if it could use the same part.


New production front fuse box, without the problem.
Factory sent out the informartion when I left the car in for service B, 1 month now.





I am thinking about what can bring the problem on:
1-I stop, put in park and switch off immediately.Usually I let engine idle for about 5 seconds, but just sometimes forget.
2-I switch on and start immediatey....I repeated this one but could not reproduce.
Today I took same trip, park on same places as yesterday, all OK.
It looks the car won't drop me next to the road at this stage.

The car had to be towed to the dealer. They told me it is the SAM and should be fixed Tuesday afternoon.
I had the car for 2 full days before this problem occurred and I was not happy to have my pre-owned (but new to me) car with only 1800 miles leave me stuck.
I'm glad there is a solution to the problem and will give the benefit of the doubt that this will be a one time thing.

I'm suspecting the sensor of the auto gear box, but I've to make the test when it happen again, 0 times in 3 months!

When it doesn't start I just remove the key and put it on again and normaly it starts right away.
